I'll try and script something tonight if I have time to make it easier to try different ciphers on the numeral to letter conversion.

Great work took! I'll definitely keep trying to solve this  Grin

Edit: so it doesn't seem like a shift cipher of any kind. I'll look over it again when the next hint is out Smiley

Now this... is a really cool idea, thanks!  Cool

Edit - I think I got your hint 1 already, but I could just be nuts... We'll see where this goes.  Cheesy

Edit 2 - People can verify the hash of their phrase(s) here - http://hash.online-convert.com/sha256-generator

One coin to rule them all
The contest is over - pawnshop770 is the winner!

Dear Forum members,
This contest is a tribute to the upcoming 2016 bitcoin reward halving. In my opinion is the block halving one of the corner stones in the bitcoin design - as it implements the finite supply of bitcoins. The winner of the contest will get a collectible coin.

Prize:
2012 Casascius blank (DIY style - no digital value)
+ 0.021 BTC (10 satoshi for each block mined since last halving)



Generate your own private key and seal it behind the included sticker, load the coin with BTC and you will have a special self-assembled halving coin.

How to solve the puzzle:
The goal is to find a specific phrase; the first person to post the correct phrase in this thread wins.

I will publish a series of hints at random times until someone solves the puzzle; it is indeed possible to solve the puzzle using the first hint alone. The duration of the contest is from now and until halving day, the last and final hint that more or of less gives the solution directly will be published on halving day.

The solution:
The sha256 sum of the winning phrase is:
Code:
f0deae019b5273e2a9b309486a7c0da50da279c28bc3bac43caf6a5eb51ad237

Rules:
  • Entry is free - anybody can participate.
  • Spamming random guesses in the thread is not allowed (check the sha256sum of your guess instead).
  • Signature spam will be reported.
  • Free discussion on how to solve the puzzle is allowed, if you are a serious contender.
  • The winning phrase must be posted in a new unedited post to be valid.
  • The coin will be shipped free of charge to winner with a regular untracked letter, I assume no liability if the letter is lost, however tracked shipping will be available at cost on the winners expense.
  • The BTC part of the prize will be paid directly to any address the winner specify and the tx id will be published in the thread.

In case problems arise with the rule set, then will I do my best to choose a fair solution, keep in mind that I am using my own time and means to do this contest and my intention is only to do something fun for our community.
  
Good luck, have fun!

Kind regards,
TookDk
